I've tested my failover setup on back-ldap instead of back-meta.
It (back-ldap) seems to perform correctly, no deadlocks have occured 
during heavy testing throughout 2.5 weeks :-)

I propose to put a note into documentation about back-meta that it is no 
longer maintained, doesn't work properly, and is deprecated.

Currently it is advertised as a supplement and improvement over 
back-ldap! This is from slapd-meta manpage distributed with OpenLDAP 2.2.14:

"This  backend has been designed as an enhancement of the
ldap backend.  The two backends share many features (actually they also
share  portions  of code).  While the ldap backend is intended to proxy
operations directed to a single server,  the  meta  backend  is  mainly
intended  for  proxying of multiple servers and possibly naming context

The same thing goes for slapd-ldbm; as far as I understand from looking 
at some threads, LDBM backend is deprecated and not maintained anymore, 
and is superceded by  BDB backend.
So I propose also adding some info to slapd-ldm manpage that its use is 
note recommended and slapd-dbd is suggested as a replacement.
